Abstract: PREVAILING TORQUE LOCK NUT AND    METHOD OF FORMING SAME                 ABSTRACT OF THE DISCLOSURE          A tri-lobular, all metal, prevailing torque nut is disclosed providing a cone having three locking sections, each of which extends around the threaded opening for about one-third of the surface of its thread.  Each locking section provides a minimum radial distance at its center and extends with gradually increasing radial distance to the ends there-of.  When the nut is threaded onto a mating threaded fasten-er, portions of each locking section are radially displaced from their unstressed condition to the circular shape of the mating fastener, producing frictional engagement between the nut and the fastener to resist unintentional loosening.  Each locking section is arranged so that it provides a maximum resistance to deflection at its center and decreasing resis-tance to deflection at locations progressively spaced from the center so that excessive pressures are not developed which would tend to produce excessive wear or permanent deformation.  Consequently, the locking torque or friction is maintained at satisfactory levels, even when the nut is assembled and disassembled with a mating threaded fastener a number of times.  The nut is produced by forming a nut blank with a cone having three lobes symmetrically positioned around the cone which are deformed radially inward during staking to produce the locking sections along the threaded passage adjacent to the cone end of the nut.

Abstract: Abstract of the Disclosure The invention concerns new solid supports  for proteins con-sisting of nitrocellulose sheets containing a replica of an electro-pherogram of proteins as obtained by electrophoretic separation in a gel.  Faithful replica of such electropherograms on the nitrocellulose support can be obtained by contacting the gel with a nitrocellulose sheet and applying an electric field perpendicular to the plans of the gel causing an electrophoratic migration of the proteins toward the nitrocellulose sheet where the proteins are adsorbed.  The process is easier to perform than similar procedures described in the art. Various analytical problems and especially immuno-assays, for instance enzyme immuno-assays or such involving radioactively labeled indicators, can be made with the new solid supports.

Abstract: Abstract A video display terminal is disclosed which may simultaneously display graphics and alphanumerics on the same screen and in superimposed relationship.  The terminal may take the form of an intelligent, processor driven terminal having a conventional bus architecture.      Data may be inputted by way of a keyboard or other peripheral, such as a host computer, and stored in a read/write memory, such as a random access memory (RAM).          Data stored in the RAM may be outputted and displayed on the terminal display screen.  In addition, graphics picked up by a closed circuit TV camera may be dynamically displayed on the terminal screen in real time.  The graphics information may then be frozen and transmitted to a remote location, such as a host computer, for long term storage.  The static graphics thus recorded can be called up and redisplayed on command at the same or a different video display terminal communicating with that host computer.  Alphanumeric information associated with that graphic image may also be entered at the terminal and recorded at the host computer.  Both the graphics and alphanumerics may then be simultaneously displayed in superimposed relationship, if needed, on a video display terminal.  One particular application of this system is in signature verification such as might be used by a teller at a branch bank or by a sales clerk in a department store for validating signatures.

Abstract: METHOD AND APPARATUS FOR SEPARATING              PARTICULATE MATTER FROM GASES               Inventor:  Joseph G. Wilson Abstract of the Disclosure A centrifugal separator has an outer tube and an inner tube concentrically positioned therein, forming an annular gas inlet channel between the outer and inner tubes, and slots are defined in the inner tube to provide communica-tion between this annular channel and the space within the inner tube.  A collection chamber for collecting particulate matter and for allowing the flow of bleed gases is provided towards the bottom of the annular channel.  Transverse dis-charge means communicate with the collection chamber for removing material therefrom.  The separator includes at least one swirling vane for imparting swirling motion to gas flowing in the annular channel.  Separation of particulate matter from the swirling gas due to centrifugal force occurs when the gas initially enters the annular channel and as the gas swirls within the annular channel.  Further separation of particulate matter occurs when the swirling gas in the channel experiences a sudden change in flow direction during entering the slots in the inner tube.  Clean gas discharge means are provided at the bottom of the inner tube so that clean gas exits the separator from below.  A plurality of such centrifugal separators are mounted in a pair of upper and lower parallel tube sheets located within a separator vessel.  The tube sheets define a main separation chamber therebetween, with a gas inlet chamber thereabove, and a clean gas discharge chamber therebelow.  Gas containing particulate matter enters the inlet chamber of the vessel from above, passes directly into the multiple separators in the separation chamber, and is discharged downwardly through the bottom discharge chamber.  Means to remove separated particulate matter and bleed gas from the separation chamber are provided.

Abstract: ABSTRACT OF THE DISCLOSURE     Methods and compositions are provided for asymecrically donating an oxygen atom to a pair of electrons to produce an asymmetric product.  Specifically, a metal alkoxide is used as a catalyst, where the metal has a coordination number of at least four, and at least one, usually two, of the alkoxide groups bonded to the metal are bonded to asymmetric carbon atoms.  The metal catalyst is employed in conjunction with a hydroperoxide and an alkanol having a functionality with a pair of electrons capable of accepting an oxygen atom.  The resulting product is enriched in one enantiomer due to the enantioselective introduction of an asymmetric center or an enhanced rate of reaction of one of the enantiomers of a chiral alkanol.  Greatly enhanced yields of enantiomers are achieved as compared to prior enantioselective introduction of oxygen. This invention was made at least in part in the course of a grant from the U.S. National Institutes of Health (GM24551).
